cdk4-mediated phosphorylation of the retinoblastoma susceptibility protein (Rb) is stimulated by cyclin D1, an oncogene, and inhibited by p16, a candidate tumor suppressor. We examined these proteins in non-small cell lung cancer (NSCLC), which is predominantly Rb positive, and small cell lung cancer (SCLC), which is Rb negative. Most NSCLC and SCLC resection specimens and cell lines overexpres...

High blood tumor mutational burden (bTMB) was significantly associated with progression-free survival (PFS) in non-small cell lung cancer (NSCLC) patients receiving atezolizumab. However, it failed to predict overall (OS). We hypothesized that ctDNA mass-adjusted bTMB (abTMB) might benefits NSCLC immune checkpoint inhibitors (ICIs) treatment.

Background: Radiotherapy is the gold standard in the treatment of lung cancer. However, the radiosensitization of cancerous cells requires further improvement. Here, we investigated the effect of dihydroartemisinin (DHA) on the radiosensitization of non-small cell lung cancer (NSCLC) cells. Methods: Cell proliferation and cell cycle assays were carried out using A549 cells exposed to DHA. The e...

OBJECTIVE To investigate the relative expression of long non-coding RNA (lncRNA) ASAP1-IT1 (hereafter called ASAP1-IT1) in tissues and cells of non-small cell lung cancer (NSCLC) patients, so as to explore the effect of ASAP1-IT1 on the biological effect of NSCLC cells. PATIENTS AND METHODS Real-time quantitative polymerase chain reaction (qRT-PCR) was performed to detect the relative express...

Running Title: L1CAM in non-small cell lung cancer Author manuscripts have been peer reviewed and accepted for publication but have not yet been edited. Abstract Purpose: Non-small-cell lung cancer (NSCLC) is a highly metastatic cancer with limited treatment options, thus requiring development of novel targeted therapies. Our group previously identified L1 cell adhesion molecule (L1CAM) express...

PURPOSE The present study was to examine the effect of sphingosine kinase-1 (SPHK1) on chemotherapeutics-induced apoptosis in non-small cell lung cancer (NSCLC) cells, which is relatively insensitive to chemotherapy, and its clinical significance in NSCLC progression. EXPERIMENTAL DESIGN The correlation of SPHK1 expression and clinical features of NSCLC was analyzed in 218 paraffin-embedded a...

Background: Metastasis associated gene 1(MTA1) is one of the most deregulated molecules in human cancer and leads to cancer progression and metastasis. We performed a meta-analysis to determine the correlations between MTA1 expression and the clinicopathological characteristics of non-small cell lung cancer (NSCLC). Methods: We searched PubMed, Springer, Science Direct, Google Scholar and China...

PURPOSE Lung cancer (LC) is the leading cause of cancer-related deaths for both male and female worldwide. Early detection of LC could improve five-year survival rate up to 48.8% compared to 3.3% of late/distant stage. Autoantibodies to tumor-associated antigens (TAAs) have been described as being present before clinical symptoms in lung and other cancers. We aimed to identify more TAAs to impr...

PURPOSE This study aims to explore the association of CpG island methylator phenotype (CIMP) involving tumor suppressor genes on short arm of chromosome 3 (3p) with increased risk of non-small cell lung cancer (NSCLC). METHODS AND MATERIALS In this study, four NSCLC cell lines were cultured, and peripheral blood mononuclear cell (PBMC) specimens from 80 patients with NSCLC and 80 matched cont...

MicroRNA (miR)-138 has previously been demonstrated to have a suppressive role in numerous types of human cancer, including non-small cell lung cancer (NSCLC). LIM domain kinase 1 (LIMK1) is a serine/threonine kinase that regulates actin polymerization via phosphorylation and inactivation of cofilin. Previous studies have reported that LIMK1 is associated with NSCLC; however, the underlying reg...
